Light/Colors/Mirrors
1 We see most objects because light reflects off them into our eyes. 2 Light is either reflected, transmitted, or absorbed when it strikes an object. 3 Transparent = material that transmits most of the light that strikes it 4 Translucent = material which scatters light as it passes through 5 Opaque = material which reflects or absorbs all of the light that strikes it; the color of an opaque object is the color of light it reflects 6 Pigment = colored substances that are used to color other materials; pigments absorb some colors and reflect others 7 Reflection = waves bouncing back off a surface through which it cannot pass 8 The law of reflection states that the angle of incidence equals the angle of reflection 9 Plane mirror = a flat sheet of glass that has a smooth, silver-colored coating on one side; the coating reflects light forming a virtual image 10 Types of mirrors: Convex = surface curves outward/ makes objects appear smaller. Concave = surface curves inward/makes close objects appear larger/Inverts distant objects 11 The primary pigments are yellow, magenta, and cyan. 12 Mixing the primary colors of pigments in even amounts produces black pigment. 13 Mixing the primary colors of light produces white light.
14. Primary pigments absorb light, so they are the opposite of the primary colors of light.

1 We see most objects because light reflects off them into our eyes.
2 Light is either reflected, transmitted, or absorbed when it strikes an object.
3 Transparent = material that transmits most of the light that strikes it
4 Translucent = material which scatters light as it passes through
5 Opaque = material which reflects or absorbs all of the light that strikes it; the color of an opaque object is the color of light it reflects
6 Pigment = colored substances that are used to color other materials; pigments absorb some colors and reflect others
7 Reflection = waves bouncing back off a surface through which it cannot pass
8 The law of reflection states that the angle of incidence equals the angle of reflection
9 Plane mirror = a flat sheet of glass that has a smooth, silver-colored coating on one side; the coating reflects light forming a virtual image
10 Types of mirrors:
Convex = surface curves outward/ makes objects appear smaller.
Concave = surface curves inward/makes close objects appear larger/Inverts distant objects
11 The primary pigments are yellow, magenta, and cyan.
12 Mixing the primary colors of pigments in even amounts produces black pigment.
13 Mixing the primary colors of light produces white light.
14. Primary pigments absorb light, so they are the opposite of the primary colors of light.
